X-ray pelvimetry is a radiological investigation that involves the measurement of different anthropometric dimensions of the pelvis. The pelvic inlet and outlet play important role in labour outcome. The query as to whether x-ray pelvimetry has a useful predictive value regarding labour outcome prompted this study.
To determine whether the use of X-ray pelvimetry is still relevant in term pregnancy, and its reliability in predicting labour outcome.
This was a retrospective study of pregnant patients who had X-ray pelvimetry at term and successfully delivered at a rural community based mission maternity hospital between 2005-2008. Each x- ray pelvimetry report was matched with the mode of delivery of the patient. 150 patients who were found suitable had data such as age, mode of delivery, etc, extracted.
In a review of 150 X -ray pelvimetry films, 119 (79.33%) were categorised as adequate pelvis, 10(6.67%) borderline pelvis and 21 (14%) inadequate pelvis respectively based on the conclusions of the radiologist. Out of the 21 patients with inadequate pelvis, 14 (67%) had normal delivery and 7 (33%) had caesarean section. For the 10 patients with borderline pelvis, 7 (67%) had normal delivery and 3 (33%) had caesarean section.
This study has demonstrated that X-ray pelvimetry may not be accurate but has fair predictive value on mode of delivery in term pregnancy.
X线骨盆测量是一种放射学检查，涉及对骨盆不同人体测量维度的测量。骨盆入口和出口在分娩结局中起重要作用。关于X线骨盆测量对分娩结局是否具有有用的预测价值的疑问促使了本研究。
确定在足月妊娠中使用X线骨盆测量是否仍然相关，以及其在预测分娩结局方面的可靠性。
这是一项对2005年至2008年期间在一家农村社区教会妇产医院足月进行X线骨盆测量并成功分娩的孕妇的回顾性研究。每份X线骨盆测量报告都与患者的分娩方式相匹配。筛选出150名合适的患者，提取其年龄、分娩方式等数据。
在对150份X线骨盆测量胶片的回顾中，根据放射科医生的结论，分别有119份（79.33%）被归类为骨盆正常，10份（6.67%）为临界骨盆，21份（14%）为骨盆狭窄。在21名骨盆狭窄的患者中，14名（67%）顺产，7名（33%）剖宫产。对于10名临界骨盆的患者，7名（67%）顺产，3名（33%）剖宫产。
本研究表明，X线骨盆测量可能不准确，但对足月妊娠的分娩方式具有一定的预测价值。
